A hitch which preserves almost all of the rope's breaking strength by avoiding knots and sharp bends. In its most common incarnation, the rope is wrapped around a cylindrical object (e.g. the trunk of a tree) several times and the tail end is then loosely secured to the standing (rappel) end for additional safety. The number of wraps will depend on both the diameter as well as the surface of the object; the larger the object and the more friction its surface offers, the fewer wraps will be needed. If done properly, there should be no tension in the tail end, hence the name. See also entry on Animated Knots for an illustration.
